To 1N-whom it 12111.11/ com Be it known that l, Ro cr A. B. VALSH, a citizen of the United plates, residing` at St. Louis, it' ssmiri, have invented a certain new and useful .improvement in Methods and Apparatus for Wakingl Wirst-l ass, of

which the following is a full, clear7 andi exactv description, such as will enable others v skllled 1n the art to which it appertams to make and use the same7 reference being, had to the accompanying drawings, forming part of this specification, in whichm i' The figure is a. sideelcvation of an appa.- ratus for practicing my method.

This invention relates to the `manuhlcture of wire glass.

rlhe object of my invention is to provide a novel method of making wire glass and also an apparatus for n'acticing my method.

Briefly described, my method consists in forming a sheet of wire glass from three separate layers of gl ass, a piece of wire mesh being arranged between two of said layers. Preferably, the tirst layer or bottom layer is formed from one mass af molten glass and the second and third layers are formed from a separate mass of glass which is divided into two portions by the roller that forms the second layer.

Referring to the drawings which illustrate one form of apparatus for carrying` out my method, 1 designates acasting table, and 2 a smooth-surface roller arranged above the casting table at a distance therefrom equal to the thickness of the bottom layer. A

smooth-surface roller 3 is arranged above the table a distance equal to the thickness of the finished product, and an adjustable roller 4 is located intermediate the rollers 2 and 3.

To form a sheet of wire glass with an ap-v paratus of this description first dump a mass of molten glass 5 onto the table adjacent the roller 2 and then move the table longitudinally7 in the direction of the arrow so thatsaid mass will be formed into a bottom layer (3. 1When the end of the bottom layer G has arrived at a point adjacent. the roller 3 a large batch of molten glass 'is dumped onto said bottom layer and the roller f is then moveddownwardly into the position shown in full lines so that it will divide said large batch of glass into two portions 7 andy 8, a piece of wire mesh 9 having been placed on the bottom layer prior to the operation of dumping said batch of glass onto said layer. As the table continues roller 4 will spread the mass of T over the bottom'layer .to form a second or intermediate layer which covers the wire mesh secondilayer. As the wire 'mesh is coinfrom` contact with the molten glass`r said mesh will not oxidize and therefore will look 1/rightand new after it `has been embedded i". the glass. The wire meshhas a tendency to contract vand-drawthe glass in which it is embedded and this produces an irregularor uneven surface on the second layervbut this uneven surface is covered by the third layer or finishing layer so that the finished product has smooth and brilliant surfaces.

I have herein shown the wire mesh as being guided into position by a chute 10 and guide roll 11 but it will. of course5 be linderstood that the wire mesh can be introduced in various ways without departing from the spirit of my invention. If desired, the wire mesh can be inserted underneath the roller 2 prior to the operation of dumping` the mass of Ilass 5 onto the table so that the wire mesh will be forced into the bottom layer simultaneously with the operation of formingr said layer.

Having' thus described my invention, what I claim as new and desire to secure by Letters Patent is: y

, 1. The `method of makingl wire glass, which consists in forming a layer of glass, dumping' a batch of molten glass onto said layer, dividing' into two portions and rollingthem into separate superimposed layers, and arrangingr a wire mesh between two of the layers; substantially as described.

2. The method of making wire xgjlass, which consists in forming' a bottom layer of glass, dumping: a batch of molten glass onto one end of said layer, separating; said batch into a plurality of portions and forming said portions into independent layers, and embedding' a wire. .mesh in one of said layers ing same; substantially as described.

3. The method of making wire glass, which consists in rolling a mass of molten glass into a bottom layer, dumping a batch of molten glass onto one end of said layer before it has been completed, dividing said batch into two portions and rolling them into separate superimposed layers, and sito travel in the direction of the arrow, the
